  1. The multivariable model included age, sex, hypertension, dyslipidemia, diabetes mellitus, smoking, drinking, atrial fibrillation, chronic kidney disease, history of stroke, stroke subtype (cardioembolism, small vessel occlusion, large artery atherosclerosis, or others), National Institutes of Health Stroke Scale score on admission, and reperfusion therapy.
  2. Mortality was defined as death from any cause 3 months after stroke onset. Lean body mass index (LBMI) was categorized into four groups according to quartiles by sex.
  3. CI, confidence interval; FMI, fat mass index; LBMI, lean body mass index; MV, multivariable; OR, odds ratio.
  4. *Fat mass index was added to the multivariable model.
